REGENERATING THE SOFTENER UNIT
(O
PTIONAL
)
Only a 2-litre ion-exchange resin softener unit can be used
on these machines.
The resins should be regenerated at least once a week or
even more frequently depending on the hardness of the
water from the mains used to supply the machine (see
table below).
ANNUAL SANITISING
At least once a year, or more frequently according to the
use of the machine and the quality of the inlet water, the
entire foodstuff circuit system must be cleaned and sani-
tized in the following way:
- all parts of the hydraulic system in contact with food, must
be removed from the unit and fully disassembled;
- wash all parts with detergent being sure that all visible
residue and product layers are mechanically removed,
using a brush if necessary;
- all components must be soaked in a sanitising solution
for at least 20 minutes;
- the unit internal surfaces are to be cleaned with the same
sanitising solution;
- thoroughly rinse and then reinstall the parts.
Before restarting the machine, the same sanitising
procedure described in section “Sanitising the mix-
ers and the foodstuff circuits” should be repeated.

To regenerate the resins correctly do as follows:
- remove the softener unit from the cabinet and shake it
vigorously to eliminate any preferential paths which may
have formed;
- fill 0.5 Kg. of sodium chloride (ordinary table salt);
- connect the side hose union to a tap and the middle
rubber-holder to a drain point; the direction of the water
flow must be
NECESSARILY
the one shown in figure 15
- adjust the water flow in such a way as to completely
dissolve the salt in 10 litres water within 25 minutes;
- during the regeneration operation, ensure that the sof-
tener unit is always full of water, bleeding any air which
may have entered;
- at the end of this operation ensure that outlet water is no
longer salted; it is advisable to check the hardness of the
water by means of appropriate chemical reagents, the
outlet water hardness should be 0°fH.
